>> good evening. i'm bill weir. it has been said that a lottery is really just a tax for people who are bad at math. but when the jackpot hits half a billion dollars, even mr. spock might let go of the logic to go buy a $2 fantasy. yes, the odds are 1 in 175 million, and yes, this powerball payday has rolled over 16 time without hitting all the numbers. but across much of the nation and all of tomorrow, all that will be pushed aside. drowned out by the inner mantra, somebody has to win and it might as well be me. here's rhinoens. . >> reporter: everyone who lines one cash in their hands and dreams in their heads seems to have a strategy. >> just one. >> reporter: by definition, just about everyone's strategy fails. is there any formula, any mathematical anything that can give you an edge over the person in front of you in line? >> no, don't put that on camera. >> there you go and good luck.
